🤖 SCDO Agent Ledger — github.com/SCDOLAB/scdo-agent-ledger ERC-8004-format AI agent identity registry with x402 USDC pay-per-call on Base: free registration,
registration.jsonschema, live agent catalog. Live: https://scdo.com.au/agents/ · verify:POST https://scdo.com.au/agents/api/verify
SCDO has two parts, both producing blocks:
- SCDO Shard0 (EVM): an EVM chain run by a core-geth fork,
Ethash proof of work, chain ID 5680 (
0x1630). MetaMask and other Ethereum wallets work directly. - SCDO Shard1 (Classic), SCDO Shard2 (Classic), SCDO Shard3 (Classic) and SCDO Shard4 (Classic): the original sharded proof-of-work chain (go-scdo, ZPoW, cross-shard transactions).
| Network | Client | Consensus | Chain ID | Decimals | Endpoints |
|---|---|---|---|---|---|
| SCDO Shard0 (EVM) | scdo-shard0 (core-geth v1.12.23 fork) |
Ethash PoW, 2 SCDO per block + fees | 5680 (0x1630) |

SCDO Shard1 (Classic), SCDO Shard2 (Classic), SCDO Shard3 (Classic) and SCDO Shard4 (Classic): block reward 3 SCDO in the current era, dropping to 2.5 SCDO at height 9,450,000
(consensus/reward.go); 1 SCDO = 100,000,000 wen. Public P2P seed hosts (TCP + UDP, one port per
shard as above): 74.208.207.184, 82.223.19.88, 74.208.136.152, 217.160.65.210.
Add SCDO Shard0 (EVM) to MetaMask: network name SCDO Shard0 (EVM), RPC URL https://scdo.com.au/rpc/0, chain ID 5680, symbol SCDO,
explorer https://scdo.com.au.
SCDO Shard0 (EVM) (GPU, Ethash). Download the GPU mining package for Windows or Linux (NVIDIA) from
https://scdo.com.au/downloads/shard0/ (also in scdo-gpu-miner releases).
It runs your own shard 0 node plus the scdo-stratum proxy on your PC, so the blocks you find pay
your own address. Any Ethash stratum miner can connect to that local proxy.
Use the package if you want the rewards yourself.
SCDO Shard1 (Classic), SCDO Shard2 (Classic), SCDO Shard3 (Classic) and SCDO Shard4 (Classic) (ZPoW). Solo mining with your own go-scdo full node (the history is about 25 GB):
curl -fsSL https://scdo.com.au/mine.sh -o mine.sh && bash mine.sh # Linux x86_64Guide: https://scdo.com.au/quickstart.html.
SCDO does not offer a cloud-mining service; mine with your own hardware and your own address.
